I am trying to create a plotly plot from R using a ggplot object, which has custom labels.

I would like that the value for a particular data-point would be taken from labels and would be displayed only when hovering the data-point. So the plot should now have a value from 'labels' for each data point, displayed as a tooltip with mouseover. You will presumably want to do something smarter in how you assign the labels to the points, but hopefully this gets you started. Given your criteria -- that is represented as 3 and is 20 -- how about dividing by and then rounding towards 0 with trunc.

It's easier to think of it in terms of the two exposures that aren't used, rather than the five that are. As per? Here's another possible data.

You can alternatively look at the 'Large memory and out-of-memory data' section of the High Perfomance Computing task view in R. Packages designed for out-of-memory processes such as ff may help you. R prefers to use i rather than j. Aslo note that complex is different than as. You are using it to copy a list. They are still referenced by Change the panel.

For some reason the top and bottom margins need to be negative to line up perfectly. Here is the result I think you want to minimize the square of a-fptotal It's generally not a good idea to try to add rows one-at-a-time to a data. Given a list of English words you can do this pretty simply by looking up every possible split of the word in the list. Assuming that you want to get the rowSums of columns that have 'Windows' as column names, we subset the dataset "sep1" using grep.

Then get the rowSums Sub1divide by the rowSums of all the numeric columns sep1[]multiply byand assign the results to a new column "newCol" Sub This should get you headed in the right direction, but be sure to check out the examples pointed out by Jaap in the comments.

Your sapply call is applying fun across all values of x, when you really want it to be applying across all values of i. You are just saving a map into variable and not displaying it. Combining the example by Robert and code from the answer featured here: How to get a reversed, log10 scale in ggplot2? Here's a solution for extracting the article lines only. Turned out much more complex and cryptic than I'd been hoping, but I'm pretty sure it works. Also, thanks to akrun for the test data.

Do not use the dates in your plot, use a numeric sequence as x axis.The ggplot2 package is generally the preferred tool of choice for constructing data visualisations in R. The main reason for this is because of its grounding in the grammar of graphicswhich essentially breaks a plot down into a system of fully customisable coordinates and layers, enabling superior design flexibility than the base R graphics. With ggplot 2, users can produce elegant, professional-looking visualisations that communicate results powerfully to the desired audience.

However, ggplot2 runs into some limitations regarding user interactivity. This becomes increasingly problematic when creating interactive documents using R Markdown or dashboard apps in R Shiny, where interactivity is a crucial component of communicating information effectively. Fortunately, the plotly library significantly enhances the design of interactive charts in R, allowing users to hover over data points, zoom into specific areas, pan back and forth through time, and much more.

We start with a simple line chart produced using ggplot2. The data we are using in our example is anonymous sales and target data between and To begin, simply load the ggplot2 package, then build your plot see ggplot2 cheat sheet for help. This static ggplot2 chart can quickly be made interactive by simply placing it inside the ggplotly function after installing and loading plotly.

The static plot has now been brought to life. Users can now zoom, hover, pan and export the plot, and more.

However, the chart still needs some work, specifically the default tooltip the box of information that appears when hovering over a data point.

I want to edit the tooltip to display the information that we want, in a suitable format. Using the scales library, we can define the y axis in a currency format quite easily. I also divided the revenue and target by one million and rounded it to one decimal place, to make the values more readable. The date can be formatted as desired see here for date formatting options.

This plot is now looking good and is fully interactive. For example, we can zoom into specific points, and pan back and forth through time:. However, we may want to disable or hide some interactive options. Luckily, the plot interactions and mode bar above the chart are fully customisable. In this case, I would like the mode bar to display all the time as opposed to when hovered over and want the option of zooming and panning my plot only, with panning being the default option.

First, to define the default interaction, in the layout function we use dragmode :. To customise the mode bar, the config function is used.

Here, the displayModeBar can be set to static to appear all the time, or hover to appear when the cursor is over the plot.One of the most deceptively-power features of interactive visualization using Plotly is the ability for the user to reveal more information about a data point by moving their mouse cursor over the point and having a hover label appear.

There are three hover modes available in Plotly. The default setting is layout. If layout. If multiple points in a given trace exist at the same coordinate, only one will get a hover label.

In the line plot below we have forced markers to appear, to make it clearer what can be hovered over, and we have disabled the built-in Plotly Express hovertemplate by setting it to Noneresulting in a more compact hover label per point:.

If multiple points in a given trace exist at the same coordinate, only one will get an entry in the hover label. In the line plot below we have forced markers to appear, to make it clearer what can be hovered over, and we have disabled the built-in Plotly Express hovertemplate by setting it to Noneresulting in a more compact entry per point in the hover label:.

The hovermode is a property of the figure layout, so you can select a hovermode no matter how you created the figure, either with plotly. Below is an example with a figure created with plotly. If you're not familiar with the structure of plotly figures, you can read the tutorial on creating and updating plotly figures.

Hover label text and colors default to trace colors in hover modes other than unifiedand can be globally set via the layout. Plotly Express functions automatically add all the data being plotted x, y, color etc to the hover label. Many Plotly Express functions also support configurable hover text. Here is an example that creates a scatter plot using Plotly Express with custom hover data and a custom hover name. To customize the tooltip on your graph you can use hovertemplatewhich is a template string used for rendering the information that appear on hoverbox.

Hovertemplate customize the tooltip text vs. Set the horizontal alignment of the text within tooltip with hoverlabel.

The following example shows how to format hover template. Here is an example to see how to format hovertemplate in Dash. You can then use customdata inside a hovertemplate to display the value of customdata. Prior to the addition of hovertemplatehover text was controlled via the now-deprecated hoverinfo attribute.

Plotly supports "spike lines" which link a point to the axis on hover, and can be configured per axis. Spike lines can be styled per axis as well, and the cursor distance setting can be controlled via layout. Dash is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library.

The free community version was sufficient for my purposes. The Plotly site has a short introduction to facilitate getting started. You can optionally add text of your choice to the pop-up. Partly as a consequence of how variables were named in the data frames being passed to the ggplot function, I sometimes encountered difficulty getting the coordinates properly labeled. Eventually I decided the simplest solution was to suppress the display of the coordinates displaying just text and then put everything I wanted coordinate values, coordinate labels, observation labels into a single, formatted hover text entry.

The details of how I did that are the gist of this post. In the user interface file, displaying a plot is extremely simple. One of the more complicated instances in my application involves plotting a histogram of residuals from a regression model with a smoothed density curve superimposed.

Note the calls to sprintf to format the tool tips with different information for histogram bars and the density curve. As von Moltke the Elder notedno battle plan survives contact with the enemy … and no coding scheme handles all cases. One of my plots, a QQ plot of residuals, tripped me up.

I wanted to identify each point with its row name. So I resorted to an alternative approach.

The code in the user interface is unchanged. The server code looks like the following:.

Some explanation is clearly in order. That in turn is formatted by the renderPlotly function into something plotlyOutput can digest. I replace those with the row names from the data set. Finally, I have to adjust for the fact that, in a QQ plot, observations are plotted in ascending order, not in their original order.

To match the correct row name to each observation, I sort the residuals, store the sort order index vector in ixand then use that to reorder the row names.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Unfortunately nothing appears. Does anyone know what I did wrong? Unfortunately ggplot is not interactive but it can be easily "fixed" with plotly package.

You only need to replace plotOutput with plotlyOutput and then render a plot on with renderPlotly. We don't have to use any special package to introduce the interactivity to our graphs though. All we need is our lovely shiny shiny! We can just play with plotOutput options as for instance clickhover or dblclick to make the plot interactive. See more examples in shiny gallery. The second solution works great but yes And yes If we use some javaScript but pssssss don't tell anyone!

We can also use ggvis package. This package is great, however, not enough mature yet. After this post I searched internet to see whether it could be done more nicely than example 3. I found this wonderful custom tooltip for ggplot and I believe it can hardly be done better than that. Learn more.
